Traffic should be very obvious when it's within 5nm.  Distant traffic shows as just a tiny dot.  This is intentional; as ADSB transceiver utilization increases there will be a lot more traffic in the broadcast, showing a big triangle for every plane would be quite intrusive. 
Question for everyone: Other than curiosity, is there a need to see traffic >5nm distant?  If so perhaps we could create a new mode that highlighted all traffic everywhere, but we would leave the existing map modes as they are.
Thanks,
